There are a couple of key things to think about in helping children and adolescents make the transition into young adulthood and independence. One of those things is called mastery motivation and we can see mastery motivation early in life. It's the ability to persist in the face of challenge. If you're growing up with a disability, it can be harder to do things. If you are not challenged, if the environment is not set up correctly, or if you don't have the resources, then you start to feel that you can't master certain kinds of tasks.
Every educator needs to make a decision about technology they need to put in place. They're not sure if they should put Option A in place or Option B in place. This can be particularly difficult in the world of disabilities because there might not always be a perfect answer. Teachers can look to this solution, using the least dangerous assumption to make good decisions about what technology might be best.
When you don't have enough evidence about a student's performance, assume they can do whatever you're asking them to do.
